LM2678S-3.3/NOPB Product Details
LM2678S-3.3/NOPB Overview
optimized performance is achieved by utilizing the Tube package in this voltage regulator. Throughout this voltage regulator, there are 7 terminations. A SWITCHING REGULATOR analog IC is used in this voltage regulator 12v, which is the type of analog IC that this voltage regulator 12v is equipped with. The harley voltage regulator is available as a TO-263-8, D2Pak (7 Leads + Tab), TO-263CA package to save space. There are 1 outputs configured on this voltage regulator 12v. As you can see, this DC DC switching regulator generates Fixed output on its output pins. The voltage regulator 12v fits the Surface Mount mounting hole. Keeping dc to dc voltage regulator's operating temperature at -40°C~125°C TJ is essential when operating. Voltage regulator has an input voltage (Max) of 40V. A regulator with this 245 peak reflow temperature is essentially indestructible. To meet the switching regulator operation requirements, a nominal input voltage of 12V is provided. In the particular voltage regulators, the LM2678 family is represented. At 3.3V volts, voltage regulator can provide voltage. In order to operate voltage regulator, 7 pins are required. In order for this switching regulator to work properly, the output voltage should be at least 3.3VV. A maximum output current of 5A A is available to meet the switching regulator operation requirements. As a result, it is able to provide adjusting voltage regulator a maximum output voltage of 3.3V. Known as a switching DC-DC regulator, this electronic voltage regulator 12v is part of the SIMPLE SWITCHER? family. External factors do not affect voltage regulator's consumption of 4.2mA A of quiescent current. In order to ensure reliable performance, the dc to dc voltage regulator's minimum supply voltage is 8V volts. DC DC switching regulator can be operated from a voltage of 40V as its maximum supply voltage. A dc to dc voltage regulator's frequency of 260kHz is sufficient for maintaining high accuracy.
